Researchers Study Effect of 3D Printing on Materials

What is the difference between materials created by using additive technologies and traditional materials? How can we predict their properties? The research that employees of the TSU Laboratory for Physics of High-Strength Crystals have now begun with colleagues from the University of Kassel (Germany) will provide answers to these and other questions.

Additive technology is the creation of materials and products for a digital model by adding layering. Today it is becoming more common. However, there is no work yet on 3D-printing alloys that are used in the laboratory (for example, cobalt, nickel, and gallium).

- With our German colleagues, we have studied the samples of various alloys produced in a standard way, and we have very good results on the influence of magnetic field on them, - says Professor Yury Chumlyakov, head of the Laboratory for Physics of High-Strength Crystals. - And now we have decided to put another task: can we get products of complex shape with the desired properties out of these materials with a 3D printer?

The discussion of the project took place during a recent visit to TSU by Thomas Niendorf, professor at the University of Kassel, and research associate Philip Kroos, with whom the Laboratory staff has conducted joint research for over five years. This time, scientists will try to figure out how the additive technologies affect the properties of the resulting materials, how they differ from those created in the traditional way, and how to change these properties or predict them. It will help to improve additive technologies of various products in the future.

- We will try different types of alloys that we have in order to determine which is best suited for this technology. For example, the new alloys with shape memory effect. They still have not been adequately studied, but their use opens big technological advantages in medicine to create implants and stents. Therefore, this area is now being actively developed in our StrAU Smart Materials and Technologies - said Professor Chumlyakov.

Leachables are trace amounts of chemicals originating from packaging, containers, medical devices or process equipment that end up as contaminants in medicinal products or food resulting in exposure to patients or consumers.
